Produce two grain sizes with one crusher using Kleemann’s double-deck post-screening unit
The mobile cone crusher and the mobile impact crusher MOBIREX MR 110(i) EVO2 can now be fitted with a double-deck post-screening unit as an option.
Cone crushers are mainly used in hard stone while impact crushers are often used in soft to medium-hard stone and in recycling. High product quality is expected from both types of plants. Thanks to Kleemann's new optional double-deck post-screening unit it is now also possible with a single machine – without an additional screening plant – to produce two classified final grain sizes.
Double-deck post screening unit guarantees high application diversity and flexibility
The large screening surface makes effective screening possible especially for grain sizes below 7/8". The discharge height of the fine grain conveyor is designed for a maximum stockpile volume. Oversize grain can be processed in a closed material circuit via a return conveyor. As an option, the conveyor can be swivelled hydraulically by up to 100 degrees, which also makes side discharge possible. A kidney-shaped stockpile can thus be created manually.
If an application is only to produce one classified final grain size, the post-screening unit can simply be used as a single-deck version.
Wind sifters for effective cleaning
As the MOBIREX MR 110(i) EVO2 is frequently used in recycling applications, wind sifters are used here as an option. They provide better material quality because lightweight material (e.g. wood and plastic) contamination is removed from the crushed material. The airflow can be controlled precisely depending on the material, reducing manual sorting work. The wind sifter can only be used in conjunction with the post-screening unit. With the double-deck post-screening unit, a second wind sifter can be used as an option for cleaning the medium grain.
